10 Best HVAC Companies in Chelmsford, MA

Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or outdated likely needs professional attention for repairs or replacement. Watch for these indicators that your system needs service:

• Odd noises when the system turns on
• Frequent breakdowns and need for repairs
• Refrigerant leaks
• Temperature control issues or thermostat malfunctions
• Rust, corrosion, or cracking
• Uneven heating/cooling or poor air circulation
• Unusually high energy bills
• An HVAC system that's over 15 years old

If you notice any of these HVAC issues, you should have a technician inspect your system. A local professional can diagnose problems and determine whether repairing or getting a new HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Chelmsford

What you spend on HVAC installation or maintenance varies based on your system type. Common HVAC unit styles include the following:

• Split or mini-split: If your home lacks the right ductwork for central air or heating, you likely have a split HVAC system. Split or mini-split systems consist of indoor units that control the temperature in individual rooms. These interior units are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the advantage of having the capability to use either electricity or gas for power.
• Heat pump: Heat pumps exchange warm and cold air between your home and outside. They don't produce their own heat or AC, so they function best in mild climates.
• Packaged heating and air: Packaged HVAC systems are a practical choice for smaller houses. These systems have a single heating and cooling unit, normally located in an attic or basement. They're small, energy-efficient, and easy to maintain.

HVAC costs differ based on the work needed. HVAC systems are complicated and may need multiple types of maintenance. Prices for common jobs are as follows:

Ways to Save Money on HVAC Costs

It’s important to complete repairs or full-system HVAC replacements as needed, though they can be expensive. The good news is that homeowners have methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.

• Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills regularly — helps you get ahead of problems before they get too expensive.
• Keep your system clean. Cleaning your condenser fan blades, grills, indoor evaporator coil, and ductwork regularly helps your HVAC system work efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it starts to look dirty.
• Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 1–3 months. Also avoid letting debris pile up on the outside areas of your HVAC.
• Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the frequency with which you need to run your HVAC.

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial for a successful project. Partnering with an experienced, licensed contractor can offer you peace of mind and make sure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

Contact at least three HVAC companies for quotes. Explain your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

Choose an HVAC company with highly trained technicians who have proper licensing and experience. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the type of exam depends on what kind of equipment they plan to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled by the state.

Massachusetts doesn't have state-level licensing requirements for HVAC contractors. However, HVAC technicians who do certain cooling work may need a Refrigeration Technician License for larger projects.

It's also a good idea to check with your city or municipal government to learn if HVAC contractors have any local licensing requirements. You should also look at reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Choose a company with positive reviews and testimonials about good customer experiences.

Understand Work Details

It’s important to know what the work process is going to look like. For HVAC repairs, the company should explain the particular parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC system, ask your installation company to provide details on the new features, estimated installation time, energy efficiency, brand, and model. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

Reputable HVAC companies back their services with warranties. Look at warranties from different companies, keeping in mind that broader coverage is better. Look for the provider that offers the most coverage for a fair price.

Get Quote in Writing

Get written bids before starting HVAC work. The quote should cover costs for both labor and materials. Review all terms carefully before signing.
